长期固定在直立位置通常会导致其他健康受试者的足部不适和水肿。为了确定腿部活动和环境压力对水肿形成、皮肤温度（Tsk）和不适的意义，6名志愿者坐8小时，其中一条腿固定，另一条腿自发活动;一天在“海平面”（750 mmHg），一天在降低的大气压（540 mmHg）。通过水体积描记法测量足肿胀。腿部运动连续监测Vitalus计算机，足部不适估计模拟视觉量表。8小时肿胀在非活动足中平均为5.7%，在活动足中平均为2.7%（p < 0.001）。不活动脚的Tsk在4小时内趋于环境温度（21 ℃）。对于活动脚来说，这种跌倒减少了2 - 3 ℃（p < 0.025）。白天足部不适的增加在活动足中最低（p < 0.005）。高足Tsk与高足肿胀率相关。降低环境气压对足部肿胀或Tsk没有影响。它的结论是，适度的腿部活动在8小时的坐着有几个影响的循环在脚上：一些效果促进和一些防止水肿的形成。然而，最终结果是减少足部肿胀。
Prolonged immobilization in an upright position often leads to discomfort and oedema in the feet of otherwise healthy subjects. To determine the significance of leg activity and ambient pressure on oedema formation, skin temperature (Tsk) and discomfort, 6 volunteers sat for 8 h with one leg immobilized and the other spontaneously active; one day at "sea level" (750 mmHg) and one day at reduced barometric pressure (540 mmHg). Foot swelling was measured by water plethysmography. Leg movements were continuously monitored by a Vitalog computer, and foot discomfort was estimated by analog-visual scales. The 8 hour swelling averaged 5.7% in the inactive foot, and 2.7% in the active foot (p < 0.001). Tsk of the inactive foot levelled off towards ambient temperature (21.degree.C) within 4 h. For the active foot this fall was reduced by 2-3.degree.C (p < 0.025). The increase in foot discomfort during the day was lowest in the active foot (p < 0.005). High foot Tsk was associated with a high foot swelling rate. Reduced ambient barometric pressure had no effects on foot swelling or Tsk. It is concluded that modest leg activity during 8 h of sitting has several effects on the circulation in the feet: some effects promote and some prevent oedema formation. However, the net result is a reduction in foot swelling.
